Kemo AT551

The Peiying AT551 alcohol tester has been designed for all drivers who want to feel safe while sitting behind the wheel. The device is extremely comfortable, allowing you to easily store it not only in the car's glove compartment but even in your pocket. The advantage of the AT551 alcohol tester is its quick preparation for measurement and a short measurement time of just 10 seconds, with results displayed on a four-digit LCD screen. The accuracy of the Peiying AT551, which is +/- 0.05 ‰ at 0.50 ‰, depends on the electrochemical sensor that is sensitive only to alcohol. Importantly, you can change the units to %, ‰, or mg/l. The maximum display range is from 0.00 to 3.00 ‰. If this value is exceeded, the alcohol tester will display the message "HI." Additionally, when the alcohol level is exceeded, the screen will change color. The alcohol tester also features a counter for the total measurements taken, which helps calculate the recalibration time (after 12 months or after 200 measurements). The device is powered by a AAA alkaline battery, which, along with the auto-off function, is sufficient for up to 300 measurements. With a battery level indicator, you can be assured that the device will not let you down in an emergency. The set includes five mouthpieces.
